UNITED STATES PATENT OFFICE. R JAMES D. PERROTT, OF BEAVER FALLS,PENNSYLVANIA. ADJUSTABLE WINDOW-SHADE FIXTURE.

Specification of Letters Patent. Application filed May 18, 1907.

To allwhom it may concern: I

Be it known that I, JAMES D. Pnnno'r'r, a citizen of the United States,residing at Beaver Falls, in the county of Beaver and State ofPennsylvania, and useful Adjustable WVindow-Shade Fixture, of which thefollowing is a specification.

The invention relates to improvements in adjustable window shadefixtures.

The object of the present invention is to improve the construction ofadjustable window shade fixtures, and to provide a simple, inexpensiveand efficient one, adapted to permit a window shade to be raised andlowcred bodily to arrange it over any desired portion of a window, andto provide light and ventilation above the window shade.

A further object of the invention is to provide an adjustable windowshade fixture, adapted to afiord rigid supports for the window shade,when the same is arranged at the top of the window.

Another object of the invention is to provide an adjustable window shadefixture, adapted to permit the unrolled portion of the window shade tobe arranged in praccords, without materially afiecting the verticalposit-ion of the spring journal, whereby the latter will always bemaintained in proper position to be engaged by the ratchet device forholding the shade roller station- I ary.

With these and other objects in view, the invention consists in theconstruction and novel combination of parts hereinafter fully ldescribed, illustrated in the accompanying j I l drawings, and pointedout in the claims hereto appended; it being understood that variouschanges in the form, proportion, size and minor details of construction,within the scope of the claims, may be resorted to without departingfrom the spirit or sacrificing any of the advantages of the inj vention.

In the drawings Figure 1 is an elevation of an adjustable window shadefixture, I constructed in accordance with this inven tion and shownapplied to a window. Fig. i 2 is a side view, showing the supportingmember of the spring journaled in engagement with the cooperating sidecasing. Fig. 3 is a similar view, showing the supportin member out ofengagement with the side i bracket. Fig. a is a detail view of the side1 have invented a new i casing, which cooperates with the supportingmember of the spring journal. F 5 1s a detail sectional view on the linea -zr of Fig. at. Fig. 6 is a side elevation of the other side pulleyand the other supporting member. Fig. 7 is a perspective view of theside casing shown in Fig. 6. Fig. 8 is a detail sectional View on theline g y of Fig. 6. Fig. 9 is a detail perspective view of the doublepulley or sheave and the means for clamping the operating cord. Fig. 10is a vertical sectional view of the same. Fig. 11 is a detail sectionalview of the spring actuated cam for engaging the operating cord.

Like numerals of reference designate corresponding parts in all thefigures of the drawings.

1 and 2 designate supporting members, whlch receive journals 3 and 4 ofactuated shade roller 5 of a window curtain or shade 6. The supportingmember 1, which consists of a narrow strip of metal, is provided at itslower end with a clamp, consisting of a vertical portion 7 of thesupporting member and a clamping plate 8, which is connected with thesupporting member by adjusting screws 9. The vertical lower portion 7 ofthe supporting member is arranged in parallelism with the clamping plate8, and the two members of the clamp are adapted to receive between themthe flattened portion of the spring journal 3, which is firmly held bythe clamp. The supporting member is provided with an inclinedintermediate portion 10 and has a quarter turn or bend thereat toarrange the upper portion 11 in a vertical plane at rightangles to thevertical plane of the lower portion 7. The inclined portion 10 off-setsthe lower portion 7 of the supporting member 1 from the window or casing12, when the window shade or curtain is at the top of the window, ashereinafter more fully explained. The other supporting member 2, whichis also constructed of a narrow strip or piece of metal, consists of aninclined lower portion 13 and a vertical upper portion 14. The lower endof the supporting member 2 is provided with a perforation 15, forming abearing opening for the reception of the pivot or journal 4 of the shaderoller. The pivot or journal l preferably consists of a screw, but anyother suitable means may be employed for connecting one end of the shaderoller to the member 2.

The upper portions are provided at inter mediate points withperforations 16 and 17 for the reception of adjusting cords 18 and 19,which pass over guide pulleys 20 and 21 of side casings 22 and 23. Theside casing 22 is provided with front and rear side plates 2a and 25,and it is open at one side to form a recess 26 for the reception of theupper portion of the supporting member 1. It is provided within therecess with vertical shoulders 27, formed by plates 01' pieces 28arranged within the casing, as clearly illustrated in Fig. 4 of thedrawings, but the shoulders may be constructed in any other preferredmanner. The front and rear plates or pieces are spaced apart by means ofsleeves 29, arranged on rivets, or other suitable fastening devices,which connect the plates. The guide pulley 20 is mounted on a suitablepivot or spindle, arranged in bearing openings or perforations of thefront and back of the side casing 22. The supporting member 1 isprovided at the upper portion with a rounded edge 31 for guiding it intothe recess 26, and the lower edge 32 of the front plate is bent outwardat the bottom of the recess to form a flaring entrance to the same. Theupward movement of the supporting member 1 in the recess is limited by ahookshaped lug or projection 33, located at the outer edge of thesupporting member 1 at the lower end of the upper vertical portion ofthe same. The adjusting cord, when drawn taut, is adapted to hold thesupport ing member 1 firmly interlocked with the side casing 22 in theposition illustrated in Fig. 2 of the drawing. This will maintain thewindow shade in spaced relation with the window frame, and the windowshade will then be supported as firmly as an ordinary window shadehaving fixed bearing brackets.

The side casing 23 is provided with plates 34 and 35 and it hasinteriorly arranged shoulders 36, formed by inner plates 37. The platesare spaced apart by sleeves 38, and the bracket 23 is provided at oneside with a recess 39 to receive the upper portion of the supportingmember 2. The upper end of the supporting member 2 is provided with arounded or curved edge 10, and the lower edge 41 of the plate 35 iscurved outward to provide a flaring entrance to the recess of the sidebracket 23. The side member 2 is also provided at the lower end of theupper portion with a projecting substantially hookshaped lug 42 tointerlock with the outwardly curved edge of the plate 35, whereby thesupporting member 2 is firmly held in engagement with the casing 23,when the adjusting cords are placed under tension with the supportingmember 2 in engagement with the casing. The guide pulley 21 is mountedon a pivot 43 and is arranged on the plates 3 1 and 35, and a secondguide pulley 14, which receives the adjusting cord 18, is mounted on thepivot 43 between the plate 35 and a plate 45. The plate &5 is spacedfrom the plate 35 by suitable sleeves 4E6, disposed on the rivets orfastening de- Vices, which also connect the plates 3 1.and 35.

When the adjusting cords are operated to lower the window shade orcurtain, the supporting members 1 and 2 drop out of engagement with theside casings 22 and 23, and the unrolled portion of the window shadewill then he in substantially the same plane as the supporting cords,and this inward or backward movement of the lower portion of thesupporting member 1 does not materially affect the arrangement of thespring journal with relation to the ratchet device of the springactuated roller, so that the spring journal will always be in properposition to be engaged by the ratchet mechanism of the roller. Theintermediate portions of the supporting members form a fulcrum on whichthe members are adapted to rock, and when the members are lowered out ofengagement with the casing, the lower portions swing inwardly and theupper portions swing outwardly, as clearly illustrated in Fig. 3 of thedrawings.

The adjusting cords 18 and 19 extend from the side casing 23 to a pulleyor sheave &7, having a peripheral groove 18 and mounted within asupporting frame 19. A smaller pulley 50 having a peripheral-groove 51is suitably fixed to the pulley 17, and the pulleys 17 and 50 aremounted on a horizontal spindle, which is preferably in the form of abolt, as illustrated in Fig. 9 of the drawings. An operating cord 52 isarranged on the smaller pulley 50 in position to wind up the adjustingcords 18 and 19 on the pulley 17, as it is unwound from the smallerpulley 50. The weight of the window shade is sufficient to unwind theadjusting cords 18 and 19 from the large pulley 47, when the operatingcord is slackened for this purpose. As the small pulley 50 isapproximately one half the diameter of the large pulley 17, theoperating cord will move one half the distance of the adjusting cords.

The supporting frame 49, which may be mounted on the window frame orcasing at any suitable point, is preferably located at the top thereofand is provided at the bottom with a horizontal extension 53, carrying avertical plate or operating cord 52 is clamped by a spring actuated camor lever 55. The lever 55, which is arranged at an inclination, extendsdownwardly from the outer end of the extension 53 of the supportingframe, and it is provided at its lower end with a substantiallysemi-circular head, having a notch or serrated edge and forming a camfor engaging the operating cord 52. The locking lever 55 is maintainednormally in engagement with the operating cord by means of a spring jaw54:, against which the 1 56, consisting of upper and lower loops andintermediate spring coils, which are mounted on the pivot 57 of thelocking lever 55. The operating cord is adapted ,to be drawn outwardaway from the plate or jaw 5a, and the weight of the window shade issutficient to overcome the force of the spring 56, so that when theoperating cord is held out ward in such position, it may be releasedslowly to lower the window shade to the desired elevation. Any otherform of locking device may be employed for holding the op erating cord.
